Description

Technical Field

[0001] The utility model relates to the technical field of hardware screws, in particular to a hardware screw with an anti-slip effect. Background Art

[0002] Hardware screws refer to screws, but they are called differently. In fact, they are screws, screws, screws, fasteners, and standard parts. Hardware screws are made of iron, that is, carbon steel and stainless steel. When conventional screws are installed on the wall, holes are usually drilled in the wall in advance and then fixed. However, the diameter of the hole is not compatible with the screw, and the screw is easy to fall off. Utility Model Content

[0003] The utility model aims to provide a hardware screw with an anti-falling effect, so as to solve the problem that when conventional screws are installed on a wall, holes are usually drilled in the wall in advance and then fixed, but the hole diameter of the hole is not compatible with the screw, and the screw is easy to fall off.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hardware screw with an anti-slip effect, comprising a sleeve and a screw, the outer side of the sleeve is provided with a first thread groove, the inner side of the sleeve is provided with a second thread groove, one end of the sleeve is provided with a slot, the inner side of the sleeve is threadedly connected with a screw, one end of the screw is fixedly connected with a connecting column, an end cap is fixedly connected to the top of the connecting column, a protrusion is provided on the outer side of the screw, the inner wall size of the sleeve is adapted to the end diameter of the screw, an insert plate is fixedly connected to the outer side of one end of the screw, the thickness of the insert plate is greater than the width of the slot, the insert plate is conically arranged, and the sleeve is made of plastic.

[0005] Compared with the prior art, the beneficial effect of the utility model is that during use, the hardware screw with anti-slip effect is used to screw the sleeve into the installation hole on the prefabricated wall, and then the screw is threadedly connected to the sleeve through the second thread groove. In this way, during the screwing-in process, the raised portion of the screw is set to cause the inner diameter of the sleeve to be deformed, and the screw is continuously screwed in to insert the plug plate into the slot to open the slot, so that the sleeve port expands outward to ensure that the connection between the sleeve and the wall is more stable. The raised portion of the screw is set to cause the inner diameter of the sleeve to be deformed to ensure a more stable connection, so that a certain anti-slip effect can be achieved.
